Catholicism does not consider gambling or drinking intrinsically evil of itself. After all, the parish is NOT sponsoring such activities as “Gay Honeymoon Night” or even those underwear parties held in some women’s homes.
Now then- If a person has a problem with alcohol, that person should not drink. If a person has a problem with gambling, that person should not gamble. It’s like a kid with an allergic reaction, say to peanut butter. Some schools take the whole thing to the point where the schools block ANY children from bringing peanut butter. Most schools have the common sense to simply have a peanut free area. If a grown-up knows something is not good for him or her, then he or she should refrain from such places. However, most grown-ups do not have an alcohol or gambling problem, and can be expected to behave themselves in an appropriate manner.
Another aspect to consider is “fun”. It is fun to gamble. It is fun to loosen up with a cocktail or two among friends. And the parish community should be friends, or at least good acquaintances. While the Mass is lovely, we can’t attend them 24/7. Fun is allowed. Recreation is even allowed in the convent and monastery- as a little wine and alcohol now and then.
My personal favorite parish activities are Boy Scout meals (pancake breakfast, spaghetti dinner). These often involve raffles and “split the pot”. I am also fond of Ladies’ Night, which includes limited alcoholic beverages (beer, wine, malt products). The local KCs sponsor a chicken dinner and fish fries, and they can include beer.
Finally, if such a thing troubles a person so much, perhaps a non-nagging committee could present a realistic stewardship fundamentals program in the parish. Then, there would be no need for fund raisers, as everybody would contribute to the parish.
